סוּסִ֥ים מְיֻזָּנִ֖ים מַשְׁכִּ֣ים הָי֑וּ אִ֛ישׁ אֶל־אֵ֥שֶׁת רֵעֵ֖הוּ יִצְהָֽלוּ׃
Comme des chevaux repus, ils courent de côté et d’autre, hennissant chacun après la femme d’autrui.
Rashi
was turned in me into corruption Heb. לְמַשְׁחִית, lit. to a destroyer. To corruption, and it is customary for Biblical verses to speak in this manner, like (Jer. 5:8): “They were like armed stallions early in the morning.” מַשְׁכִּים is the equivalent of בְּהַשְׁכָּמַת הַבּקֶר, in the early morning.
Rashi
your neighings like the neighing of adulterous horses.
